In addition, he studies the correlation between concentrations of proteins and cytokines and histological markers of atypical cells. It was found that the concentration of histidine-rich glycoprotein in supernatants of blood cells with a special type of invasive carcinoma is higher compared with benign breast diseases. In addition, the following statistical relationships were observed in the study: negative correlation between estrogen receptor-α concentrations and integrin-1 expression; a positive correlation between the concentrations of histidine-rich glycoprotein and expression of type II collagen; a positive correlation between e-cadherin concentrations and e-cadherin expression; and a positive correlation between the concentrations of plasminogen-1 activator inhibitor and the expression of type II collagen. The production of cytokines by blood cells is identified as an index of the influence of polyclonal activators (a combination of mitogens). The study shows the difference in the index of influence on the production of IL-1RA and TNF-α between benign breast diseases with a high and low risk of malignant transformation and between benign breast diseases with a high risk of malignant transformation and breast cancer with metastases to the lymph nodes. The index of the effect of polyclonal activators on IL-1RA production increases as the prognosis of the disease worsens. As blood samples and tumors show, patients with benign breast diseases have a negative correlation between the index of influence of polyclonal activators on IL-1RA production and expression of type II collagen. In addition, patients with breast cancer as well as breast cancer with metastases in the lymph nodes have a positive correlation between the expression of e-cadherin and spontaneous and polyclonal stimulation stimulated by the production of IL-1RA. The results of the study showed that the concentrations of histidine-rich glycoprotein and IL-1RA in blood cell supernatants and the […]
